To understand what the BeOS and Haiku operating systems are, we first must remember that BeOS was developed with the multimedia user in mind. BeOS wanted to be what OS X has become today: an easy to use, attractive operating system. However, BeOS was a niche OS, destined for the media-hungry user. The percentage of audio and video applications available for Haiku is greater than the one in Linux, OS X or Windows, and the inner workings of the operating system were created in such a way, that the same multimedia passionate would find it easy to work with the user interface and files. Each application can interfere with other applications of its kind. A WAVE file selection can be dragged from a sound editor and onto the desktop, to create an audio file. Audio applications can interfere with each other via the Haiku Media Kit -- the corespondent of a Linux sound server. Applications like Cortex are a perfect example of how BeOS and Haiku deal with multimedia files: you can have more than one soundcard and use each one of those soundcards independently or separately. You can link one soundcard to the Audio Mixer, start a drum machine application and link that software to the Audio Mixer. If you want to output whatever you create with the audio application, all you have to do is drag the microphone and link it to the application's icon in Cortex.

So what? BeOS failed back then, it's hard to see how a half-assed clone could "change the world" today, competing against much more evolved operating systems. Unless the only purpose of suggesting it is to have a good laugh of course.

Nothing wrong with it being a hobbyist OS, just don't hype it as anything else based on wishful thinking and a delusional view of what software engineering is all about. We have the year of Linux on the desktop for that, there's no need to bring more guests to that party.
